It's about refusing to give up on yourself just because you're getting older. "Say what you will, wait for me to fade / I don't think about it, I don't think about it," Williams sings in the pre-chorus. "I've got things left to do and I'm nowhere near done / Not while I still have these legs."
Her exuberant defiant attitude continues in the chorus as she sings, "They say the legs will be the last to go (I'll keep dancing) / I'm still putting on a show (I'll keep dancing) / Until you do, don't do it again."
Williams does indeed keep dancing throughout the video, suggesting that she executed some key choreography with the help of numerous backup performers.
"Sometimes kids just need to go to school!" the video's director Mike Ruiz joked in the comments section.
The song title is a reference to Diahann Carroll's 2008 memoir The Legs Are the Last to Go: Aging, Acting, Marrying, and Other Things I Learn the Hard Way.
"The whole concept was Vanessa's idea," co-writer Kipper Jones said in a press release, adding that Williams knew she wanted to include Carroll's name somewhere in the song. "[Vanessa] didn't know if it was the title of the song or the lyrics or something else. I didn't find it unusual at all. That's how we came up with 'Comfort Zone' in 1991."
Earlier this month, Williams announced that his new full-length album will be released later this year.
